Are you aware that the Speech API CG has developed a proposed specification
for speech recognition and synthesis:
http://www.w3.org/community/speech-api/ and
http://dvcs.w3.org/hg/speech-api/raw-file/9a0075d25326/speechapi.html ? I
am not sure about its status and whether it is being adopted into the work
of a W3C WG. Is your suggestion to adopt it as a piece of work for this
Working Group?

Indexing, search and retrieval are applications and don't need improvements
to the HTML specification. The W3C Media Fragments WG also has developed
specifications that allow the creation of hyperlinks into time-based
multimedia documents, see http://www.w3.org/TR/media-frags/ . As URLs can
be stored as bookmarks, these use cases are already possible.

3D graphics are indeed interesting. There is a whole consortium looking at
3D graphics on the Web: http://www.web3d.org/realtime-3d/ and X3D files can
be used in browser applets. Are you suggesting we should make it more of a
native Web format? Have browser vendors expressed interest in implementing
3D graphics support natively?

I am not convinced that Web pages need media overlays. We have many years
of experience in making Web pages accessible by proving text alternatives
for certain pieces of content and by having AT communicate either existing
text on a page or provided text alternatives to a11y users. Media overlays
make sense for books where there is a linear reading experience. Web pages,
and more so modern Web applications don't generally follow a linear reading
experience and thus text and text alternatives that are associated with
user's focus seem more adequate. I would, however, suggest discussing such
needs with WAI.

Silvia.
